FIELD OF THE INVENTION

The present invention relates generally to a hinge system, and more particularly to a hinge system for use in a fixed bin in an aircraft.

BACKGROUND OF THE INVENTION

Many aircraft, including the Airbus A320 and Boeing 737, include fixed overhead storage bins, which are also known as shelf bins. The bins include a hinged door that opens upwardly. Airlines want to optimize bin space to allow passengers to put as much luggage into overhead storage bins as possible. However, as shown in FIG. 1, the hinge mechanisms in current fixed bins take up valuable bin space. Accordingly, a need exists for a fixed bin and accompanying hinge system that maximizes space.

SUMMARY OF THE PREFERRED EMBODIMENTS

In accordance with a first aspect of the present invention there is provided a hinge assembly for an aircraft overhead storage bin that includes a housing having a hinge space and a hinge opening defined therein, an arm pivotably connected to the housing within the hinge space, and a dampener. The hinge opening communicates the hinge space with an exterior of the housing. The arm is pivotable between a closed position and an open position and extends through the hinge opening such that the first end of the arm is positioned outside of the housing. The dampener includes first and second ends. Preferably, the dampener includes a cylinder having a spring or springs, dampening fluid or the like therein and a spring that extends from the cylinder. The dampener overall length of the dampener gets longer or shorter in use. The first end is connected to the housing and the second end is connected to the arm. The dampener biases the arm from the closed position to the open position. In a preferred embodiment, the arm includes a second end opposite the first end and the second end of the dampener is connected to the second end of the arm. The arm is pivotably connected to the housing about a pivot axis and the pivot axis is located between the first and second ends of the arm. The arm includes a second end opposite the first end and the second end of the dampener is connected to the second end of the arm. The arm is pivotably connected to the second housing about a pivot axis.

In a preferred embodiment, the arm is pivotable between the closed position, the open position and an over-travel position. The arm is biased from the over-travel position to the open position. The housing preferably includes a stop member that the arm contacts when the stop member is in the over-travel position. Preferably, the housing includes inner and outer housing members that cooperate to define the hinge space therebetween. The pivot axis is defined by a pivot axle that extends from one of the inner and outer housing members and the stop member is secured to one of the inner and outer housing members. The stop member can be unitary with (monolithically formed with) or attached to the housing member.

In a preferred embodiment, the entire dampener is movable between a normal position and an over-travel position (as opposed to the arm portion of the dampener member extending outwardly or inwardly). The dampener is in the normal position when the arm is in the closed and open position and the dampener is in the over-travel position when the arm is in the over-travel position.

In a preferred embodiment, the stop member is movable between a first stop position and a second stop position. In this embodiment, the stop member is biased to the first stop position. The arm contacts the stop member when the arm is in the open position and the stop member moves to the second stop position when the arm is moved to the over-travel position (where the arm is still in contact with the stop member).

The present invention includes an overhead storage bin that includes a hinge system a with first and second hinge assemblies. Generally, the bin includes a bottom or shelf, first and second side or end panels, a top and a door that is hingedly connected to the bin, and the first and second side panels, in particular. The door includes a latch that cooperates with a catch on the shelf to hold the door in the closed position. Any type of latch system is within the scope of the present invention. As described herein, in a preferred embodiment, the hinge assembly is used in an aircraft overhead storage bin. However, this is not a limitation on the present invention, and the hinge assembly can be used with any type of door or cover that is moveable between a closed and opened position.

The side panels include a cut out or recess therein in which the hinge assembly is received or seated. As a result, the hinge assembly is flush with or almost flush with the inside surface of the side panel of the bin. This provides extra room within the bin interior compared to the prior art.

In a preferred embodiment, the hinge assembly includes inner and outer or first and second housing members that house or sandwich a lever arm and dampener in a hinge space therebetween. The lever arm includes a second end to which the damper is attached and a first end that attaches to the door. The lever arm is pivotally connected to one of the housing members at a pivot axis between the first and second ends. The end of the dampener opposite the lever arm is secured to one of the housing members.

In a preferred embodiment, the hinge assembly is designed to house most or all of the components within the thickness of the side panels. It also includes over travel of the lever arm to enable two open door positions, as described below. These open positions include one normal open angle (similar to the open angle of the prior art) to accommodate ergonomic or normal reach and a second “over rotated” or fully open position to allow for larger content loading.

The door, lever arm and dampener move between a closed position, an open or intermediate position, and a fully open or over-travel position. In the closed position the spring dampener is compressed and is biased toward the intermediate position and is being held in the closed position by the latch engagement of the door on the shelf or bottom of the bin.

The door is moved to the intermediate position when the latch is disengaged from the catch and the spring dampener extends, thereby moving the lever arms and the door to the intermediate position. This position allows for proper ergonomics of reach when closing the door (meaning the average person can reach and close the door). The first end of the lever arm is operationally connected to a slot that captures the ends of and/or provides clearance for the pivotal movement.

The fully open or over-travel position occurs when an oversized bag is loaded or unloaded and pushes the door further open or up (which further pivots the lever arm). A person can also push the door up. The door only moves or pivots to this position when force is applied thereto. Once force is no longer applied, the door returns to the intermediate or open position. This can be achieved by having the dampener attached to a slide mechanism allowing for additional rotation of the lever arm. It can also be achieved by moving the dampener beyond its normal (at rest) position.

Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same, FIGS. 1-6 show an overhead storage bin 10 that includes a hinge system 11 with first and second hinge assemblies 12 that can be used for opening and closing the door 14 of the overhead storage bin 10. Generally, the overhead storage bin 10 includes a bin housing 16 that includes a top 18, a bottom 20 and first and second end panels 22 that cooperate to define a bin interior 24. The bin 10 also includes a latch system 26 that maintains the door 14 in the closed position. As shown in FIG. 1, the door 14 is movable with respect to the bin housing 16 between a closed position and an open position.

In a preferred embodiment, the right and left or first and second hinge assemblies 12 are connected to the first and second end panels 22. As shown in FIG. 3, the first and second hinge assemblies 12 can be positioned in a cut-out 28 defined in each of the end panels 22. For example, the cut-outs 28 can be defined in the upper inboard corner of the end panels 22, as shown in FIG. 1. Threaded fasteners can be inserted through openings 35 in the housing 32 and openings 37 in the end panel 22. The hinge assemblies 12 each include an arm 30 that is connected to the door 14. The arms 30 travel with the door 14 between the closed and open position (and to the over-travel position, as described below). It will be appreciated that the door 14 and arms 30 are biased to the open position. Therefore, when the latch system 26 is released, the door automatically moves to the open position.

The hinge assembly 12 will now be described. As shown in FIGS. 2-6, the hinge assembly 12 includes a housing 32 having first and second housing members 32 a and 32 b that include a hinge space 34 defined therein. The housing 32 also includes a hinge opening 36 is defined therein that communicates the hinge space 34 with the exterior of the housing 32. The hinge assembly 12 also includes an arm 30 pivotably connected to the housing 32 within the hinge space 34. The arm 30 includes first and second ends 30 a and 30 b and is pivotable between a closed position (FIG. 4) and an open position (FIG. 5) that coincide with the closed and open positions of the door 14. The arm 30 extends through the hinge opening 36 and the first end 30 a of the arm 30 is positioned outside of the housing. The hinge assembly 12 also includes a dampener 40 that includes first and second ends 40 a and 40 b. The first end 40 a is connected to the housing 32 and the second end 40 b is connected to the arm 30. The dampener 40 biases the arm 30 from the closed position to the open position. Therefore, in the hinge system 11, the first and second dampeners bias the arms and the door to the open position.

As shown in FIG. 4, in a preferred embodiment, the second end 40 b of the dampener 40 is connected to the second end 30 b of the arm 30. In another embodiment, the dampener can be connected to the arm at a point between its first and second ends. The arm 30 is pivotably connected to the housing 32 (and one of the first or second housing members 32 a and 32 b) about a pivot axis A1 that is located between the first and second ends 30 a and 30 b of the arm 30. Preferably, the housing 32 includes a pivot axle 42 that extends from one of the inner and outer housing members 32 a and 32 b (or that extends between them) and that defines the pivot axis A1. The pivot axle 42 is received in a pivot opening 43 defined in the arm 30. The door 14 can be attached to the arms 30 via brackets 45. The brackets 45 can connect to the arms 30 via a pocket 47 defined therein.

In a preferred embodiment, the arm 30 is pivotable between the closed position, the open position and an over-travel position (FIG. 6). The arm 30 is biased from the over-travel position to the open position. In a preferred embodiment, the dampener 40 biases the arm 30 from the over-travel position to the open position. In a preferred embodiment, the housing includes a stop member 48 that the arm 30 contacts when it is pushed or moves to the over-travel position. The stop member 48 preferably protrudes outwardly from one of the housing members.

As shown in FIG. 3, the first and second ends 40 a and 40 b of the dampener 40 include connection openings 44 defined therein. Preferably, the connection openings 44 are larger than the connection members 46 that fit therein, thereby providing clearance and allowing the dampener 40 to move in an axial direction. FIGS. 4 and 5 shows the dampener 40 in the normal position (note the space S1) between the connection member 46 and the connection opening 44. In FIG. 4 the dampener 40 is collapsed and in FIG. 5, the dampener 40 is expanded to its maximum stroke. However, in both collapsed and expanded configurations space S1 is evident due to the position of the ends of the dampener with the respective connection members. FIG. 6 shows the dampener 40 in the over-travel position (note the space S2) between the connection member 46 and the connection opening 44. In use, when the door 14 and arms 30 are pushed to the over-travel position, the entirety of the expanded dampeners 40 move axially between the normal position and the over-travel position. When the door 14 is released, the dampeners 40 move back to the normal position.

FIGS. 7-8 show an embodiment of the invention where the stop member 48 is movable and biases the arm 30 from the over-travel position to the open position. In this embodiment, the stop member 48 is movable between a first stop position (FIG. 7) and a second stop position (FIG. 8). In use, the arm 30 contacts the stop member 48 (and is therefore stopped) when it reaches the open position. Then, when a user or luggage pushes the door 14 to the over-travel position, the stop member 48 moves to the second stop position. When the door is released, the stop member 48 pushes the door or biases the door back to the open position. This can be accomplished by including a spring 50 or springs that biases the stop member 48 to the first stop position and is compressed when the arm 30 pushes against the stop member 48.

In an embodiment, the over-travel position can be omitted. In another embodiment, stop member can only be included on one of the first and second hinge assemblies. In another embodiment, the housings can comprise or be unitary with the end panels.
